I work in a space adjacent to change management (ERP implementation) and honestly, be happy and kind. These questions are the absolute default ones of humans attempting to puzzle out a paradigm shift. And the fact they're here and they're feeling loved enough to actually ask for help with their new mental model of it is about eight degrees better than it could have been.

So my answer is: it's just like r/games, r/gaming, r/videogames, r/patientgamers. They are all the same subject matter with overlapping content and userbases, with potentially wildly different moderation biases and groupthinks. And that was all on one centralised Reddit! You subbed to some, or all of them, as you saw fit, you maybe even managed a multireddit to group them! It's just the same here except they're on different instances and soon, enhancements to Lemmy pending, will be just as seamless to manage.
